With temperature increasing, physical and chemical<br />changes occur that are related to the evaporation of solvent water (20–110°C), followed by the release of constitution<br />water, and finally intermolecular dehydration (110–230°C). In this temperature range, processes that are mainly reversible<br />take place. Within a temperature range of 450–826°C, polymer chains are decomposed, including the decomposition<br />of side chains. Within a temperature range of 399–663°C, polymer composition decomposition can be observed (FTIR,<br />DRIFT), and gas products are generated from this destruction (Py-GC-MS).</p>}, number={1}, journal={Journal of Casting & Materials Engineering}, author={Grabowska, Beata and Kaczmarska, Karolina and Bobrowski, Artur and Żymankowska-Kumon, Sylwia and Kurleto-Kozioł, Żaneta}, year={2017}, month={Mar.}, pages={27} }
